quinoa salad with yams and apples

adapted from Food and Wine
Another fall salad we just tried. Although hearty enough for a light lunch also makes a light and refreshing appetizer or side dish.

serves 10-12 (I halved the recipe)

INGREDIENTS
1/2 cup olive oil
1 1/2 cups quinoa
1 1/2 pounds yams, peeled and cut into 3/4-inch dice
freshly ground pepper
1/4 cup apple cider vinegar
2 large granny smith apples, cut into 1/2-inch dice
1/2 cup chopped flat-leaf parsley
1/2 medium red onion, thinly sliced
8 cups baby greens (about 6 ounces)

1. Preheat oven to 400F. In a large saucepan, heat 1 Tbsp. of the olive oil. Add the quinoa and toast over moderate heat. stirring, for 2 minutes. Add 2 1/2 cups of water, season with salt and bring to a boil. Cover and simmer for 16 minutes (if all water is absorbed sooner, add additional 1/2 cup). Remove from heat and let stand for 10 minutes. Fluff quinoa, spread it out on a baking sheet and refrigerate at 20 minutes or more.
2. Meanwhile, on a baking sheet, toss the yams with 1 Tbsp. olive oil and season with salt and pepper. Roast for about 25 minutes, stirring once, until golden and softened. Let cool.
3. In a large bowl, whisk the remaining 6 Tbsp. of oil with the vinegar; season with salt and pepper. Add quinoa, yams, apples, parsley, onion and greens. Toss well and serve.

note: to make ahead prepare quinoa and yams. They can be refrigerated for up to 2 days.
